There is a post about all of the problems from quite a while back. With the patches and WA, I haven't heard of too many more problems with saving anymore. I do know from a few people with laptops, that they had had problems the more they saved the worse it got. I am not quite sure why laptops are like that, I know myself, like many others have lost games, but it has been a while back. I took some advice from Metro, I believe and turned down all my specs and turned off my game after a few hours and doing so, I have not lost anything yet, thank heavens. Good luck and I hope you can find out the reason why.
